"21. In summary, the power to stay criminal proceedings as an abuse of process is an important though exceptional remedy to be exercised with care and restraint. A stay of proceedings is the exception, not the rule; it is a measure of last resort. 22. There are two species (or limbs) of abuse justifying a stay, each of which is separate and distinct. The first is when a fair trial is not possible. The second is where it offends the court's sense of justice and propriety, or public confidence in the criminal justice system would be undermined, for the defendant to be tried in the particular circumstances of the case. The abuse must amount to an affront to the public conscience."
"30. But in considering such powers to alleviate prejudice, Brooke LJ (at para 27) emphasised the need for sufficiently credible evidence, apart from the missing evidence, leaving the defence to exploit the gaps left by the missing evidence. The rationale for refusing a stay is the existence of credible evidence, itself untainted by what has gone missing. 31. In the instant appeals, the missing evidence and the evidence which the jury had to believe cannot be distinguished in that way. That which was missing, T's application to the CICA, was part of the material by which her credibility could be assessed." (Emphasis added)
